For he wounds, but he binds up; he shatters, but his hands heal. Job. 5.18

One of the most remarkable things about God is his amazing ability/penchant for redeeming suffering (the cross being the ultimate example). Whatever you have suffered, whatever pain you are going through right now, none of it is in vain, none of it will be lost. The Lord will redeem it. Your strength and ability to minister to and care for others will be founded on the redemption of your own suffering, anointed by the lamb who was slain, who identifies with those in pain.
